Description

Technical Field

[0001] The invention belongs to the field of geophysical prospecting technology, and relates to a physical point setting out quality monitoring technology in geophysical surveying, in particular to a method for avoiding repeated setting out of physical points of the same surface element and its application. Background Art

[0002] With the continuous advancement of exploration technology and the rapid development of high-precision, low-cost, and efficient geophysical exploration models, the scope of seismic exploration is also expanding. The expansion of seismic data acquisition operations into complex areas such as mountainous areas, swamps, and urban areas requires seamless exploration technology, highlighting new demands on geophysical exploration equipment and technology. Due to the complex and diverse terrain, especially during field survey and stakeout operations in mountainous and other complex terrain, construction workers often encounter various obstacles (such as mountains, rivers, buildings, and mountain bodies), necessitating the offset of pre-set physical points. In current construction methods, surveyors typically perform this offset on-site. Construction requirements dictate that only one physical point stake number can be measured and staked out within the same bin, and multiple points cannot be staked out repeatedly. However, in field construction projects, the complex terrain often makes it difficult to directly determine whether the offset physical point is in the same bin as the existing physical point.

[0003] After shifting the physical point positions, construction workers return to camp and hand over the survey results to the surveying office calculator for data review and processing. If any unqualified physical points are found, on-site construction workers are often required to re-measure and stake out the points the next day. This rework significantly impacts seismic acquisition production scheduling, manpower, and material resources, wasting construction time and delaying production progress. Similarly, this problem can arise during unmarked production processes such as alignment, drilling, and seismic sources. If subsequent data processing requires additional shots and re-collection, a significant amount of manpower and material resources will be wasted on re-laying the alignment and performing additional excitation acquisition, resulting in low efficiency in the stakeout process.

[0004] With the rapid development of software, communications, artificial intelligence, and cloud computing, intelligent physical point staking in petroleum geophysical exploration has become an inevitable trend. Therefore, exploring a method to avoid repeated staking of physical points within the same bin and its application is of great significance for improving the efficiency of the staking process and effectively reducing exploration costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method and application for avoiding repeated layout of physical points in the same surface element, so as to avoid the problem of multiple physical point pile numbers in the same surface element and improve the informatization and intelligence of the quality control of geophysical physical point layout operations.

[0006] Another object of the present invention is to provide a method for avoiding repeated staking of physical points of the same bin, so as to improve the efficiency of the staking operation and meet the demand of reducing exploration costs.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A method for avoiding repeated lofting of physical points of the same bin, characterized in that the method comprises the following steps performed in sequence:

[0009] S1. Collection of physical point data

[0010] After on-site construction personnel measure and stake out physical points, they upload the information of the physical points to the data center;

[0011] S2. Processing of physical point data

[0012] Based on the physical point information received by the data center and according to the seismic exploration bin division rules, the data center performs same bin calculation and obtains same bin calculation results;

[0013] S3. Feedback on the calculation results of the same facet

[0014] Based on different calculation results of the same-surface elements, the data center provides different feedback to the on-site construction personnel.

[0015] As a first limitation of the method for avoiding repeated setting out of physical points of the same bin, in step S1,

[0016] The information of the physical point includes stake number information, coordinate information, positioning accuracy information, corresponding bin division rules and grid number information;

[0017] The data center is a server-based intelligent earthquake team data center.

[0018] As a further limitation of the first limitation of the method for avoiding repeated staking of physical points of the same bin, the server includes a local server or a cloud server.

[0019] As a second limitation of the method for avoiding repeated staking of physical points in the same bin, in step S2, the seismic exploration bin division rule is as follows: selecting a design point as a starting point, dividing the work area into a plurality of grids according to line intervals and their spacings, point intervals and their spacings, and survey line orientations, with each grid representing a bin, and further numbering each bin;

[0020] The same-surface element calculation includes the data center obtaining the spatial position relationship between physical points based on the information of the physical points, and further performing the same-surface element calculation by comparing the grid relationship data;

[0021] The grid relationship data comparison described in the present invention can realize unattended automatic comparison at the data center end and support automatic comparison of all seismic exploration projects.

[0022] As a third limitation of the method for avoiding repeated lofting of same-surface element physical points of the present invention, in step S3, the different same-surface element calculation results include two situations: repeated physical points in the same surface element and no repeated physical points in the same surface element;

[0023] The data center provided different feedback to the on-site construction personnel, specifically:

[0024] ① When the calculation result of the same surface element shows that there are repeated physical points in the same surface element, the data center will provide feedback to the on-site construction personnel in the form of an alarm prompt;

[0025] ② When the calculation result of the same surface element is that there are no repeated physical points in the same surface element, the data center will prompt that the data upload is successful.

[0026] The present invention also provides an application of the above method for avoiding repeated staking of physical points of the same bin, which is applied to physical point staking and markerless construction in the field of geophysical exploration.

[0027] As an application of the above method, the markerless construction includes markerless deployment of geophones, markerless drilling and markerless acquisition of seismic sources.

[0028] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared with the prior art:

[0029] ① The method proposed in this invention to avoid repeated staking of physical points in the same bin does not require the use of spatial analysis functions of other GIS software. This method is mainly based on the physical point information uploaded by the user in real time. The data center checks whether there are already physical points in the same bin by comparing grid relationship data. If the bin has already been staked out, an alarm will be issued to the second staker, thereby ensuring that there is only one physical point result data in the same bin, thereby ensuring the quality of the physical point results;

[0030] ② The method proposed in the present invention for avoiding repeated staking of physical points of the same bin can timely discover and handle unqualified situations in the staking construction of physical points during the geophysical surveying production process, and can issue alarms to promptly correct problems when they are discovered, thus avoiding rework and ensuring that the progress of each process of the geophysical exploration project is more efficient.

[0031] ③ The method for avoiding repeated layout of physical points in the same element proposed in the present invention can be applied to the measurement and layout, unmarked construction and other layout and collection sites of the seismic team in the field of geophysical exploration. It can immediately check the deviation points and missing points, and realize on-site discovery and on-site problem solving, thereby solving the difficult problem that has plagued the seismic team for many years, that is, rework after multiple physical point pile numbers appear in the same element, meeting the demand for reducing exploration costs and improving construction efficiency. The application of this method can also promote the development of informatization and intelligentization of production quality control in the field of geophysical exploration.

[0032] In summary, the method provided by the present invention for avoiding repeated layout of physical points of the same face element can timely discover and handle unqualified situations in the layout construction of physical points in the geophysical measurement production process, and promptly correct problems when they are discovered to avoid rework. This method can be applied to layout and collection sites such as physical point layout and unmarked placement of detectors, unmarked drilling, and unmarked acquisition of seismic sources in the field of geophysical exploration, ensuring that there is only one physical point result data in the same face element, thereby ensuring that the progress of each process of the geophysical exploration project is more high-quality and efficient. At the same time, it can also promote the development of production quality control in the field of geophysical exploration towards informatization and intelligence.

[0036] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. It should be understood that the embodiments described are preferred examples of the present invention and are only used to explain the present invention and are not intended to limit the present invention.

[0037] Example 1: A method for avoiding repeated placement of physical points on the same bin

[0038] This embodiment is a method for avoiding repeated placement of physical points of the same bin. The flow chart is as follows: Figure 1 As shown, the method includes the following steps performed in sequence:

[0039] S1. Collection of physical point data

[0040] After on-site construction personnel measure and stake out the physical points, they upload the stake number information, coordinate information, positioning accuracy information, bin division rules, and grid number information of the staked physical points to the intelligent seismic team data center based on a local server or cloud server;

[0041] The positioning accuracy information includes RMS value, PDOP value, HDOP, horizontal accuracy, vertical accuracy, solution type and epoch number;

[0042] The intelligent earthquake team data center based on the local server or cloud server is responsible for receiving, processing and storing the information of the physical points;

[0043] S2. Processing of physical point data

[0044] Based on the received physical point information and in accordance with the seismic exploration bin division rules, the intelligent seismic team data center obtains the spatial position relationship between the physical points and performs same-bin calculation by comparing grid relationship data to obtain same-bin calculation results;

[0045] The seismic exploration bin division rule in the present invention is as follows: select a design point as the starting point, divide the work area into several grids according to the line interval and its spacing, point interval and its spacing, and the survey line orientation, and one grid represents one bin, and further number each bin;

[0046] It should be noted that the intelligent seismic team data center stores several bin division rules, such as normal bin division rules, encrypted bin division rules, well-gun bin division rules, and source bin division rules. When the intelligent seismic team data center receives the bin division rules of the uploaded physical point, it can retrieve the bin division rules corresponding to the physical point in the server and further use them for the same-bin calculation of the physical point.

[0047] Preferably, the grid relationship data comparison in this embodiment can realize unattended automatic comparison at the data center end, and supports automatic comparison of all seismic exploration projects;

[0048] In this embodiment, the same-surface element calculation is implemented by the geophysical surveying handheld software (abbreviated as: GeoSNAP-SSField-A), and the software registration number of the software is 2019SR0825256.

[0049] S3. Feedback on the calculation results of the same facet

[0050] Based on different isosurface element calculation results, the intelligent earthquake team data center provides different feedback to on-site construction personnel:

[0051] ① When the calculation result of the same-surface element shows that there are repeated physical points within the same surface element, the intelligent seismic team data center will feedback to the on-site construction personnel in the form of alarm prompts including control equipment vibration, warning sound, prompt message, etc. The on-site construction personnel will make timely corrections to the existing problems to avoid the measurement results being re-shifted and set out due to the unqualified same-surface element problem;

[0052] ② When the calculation result of the same-surface element is that there is no repeated physical point in the same surface element, the data center will prompt that the data upload is successful, indicating that the location of the physical point is appropriate and does not need to be offset.

[0053] Example 2 Application of the method for avoiding repeated setting out of physical points of the same bin

[0054] The method proposed in this invention to avoid repeated staking of physical points of the same plane element can not only be applied to physical point staking in the field of geophysical exploration, but can also be used in conjunction with markerless construction. Markerless construction is to integrate the original measurement and staking process into various processes of geophysical exploration production such as arrangement, drilling and acquisition, so as to achieve simultaneous measurement and positioning with detector deployment, drilling construction and even seismic acquisition. Therefore, the method to avoid repeated staking of physical points of the same plane element can be applied to physical point staking and markerless construction. The structural block diagram of the application of this method is shown in the figure below. Figure 2 shown.

[0055] Figure 2 The application includes: geophysical exploration-specific measurement software 110 including the method for avoiding repeated layout of physical points of the same plane element as described in Example 1 of the present invention, markerless construction software 120 including the method for avoiding repeated layout of physical points of the same plane element as described in Example 1 of the present invention, seismic source markerless construction system 130 including the method for avoiding repeated layout of physical points of the same plane element as described in Example 1 of the present invention, and intelligent seismic team data center 140 based on local server or cloud server; wherein 110 and 140, 120 and 140, 130 and 140 realize communication and interconnection through self-organized local area network, 4G / 5G public network, etc.

[0056] (1) The method of avoiding repeated placement of physical points of the same facet element is applied to physical point placement

[0057] In this embodiment, the surveying team applies the above-mentioned method of avoiding repeated staking out of physical points of the same bin to perform physical point staking out, specifically:

[0058] The surveying team uses physical point acquisition equipment to optimize, store, encrypt and upload field physical points to the intelligent seismic team data center 140 based on a local server or a cloud server. The physical point acquisition equipment has built-in geophysical exploration-specific measurement software 110. The geophysical exploration-specific measurement software 110 is based on geographic information, developed using the Android Studio development platform and the SQL Server database, and is developed using the JAVA language. It also includes the method for avoiding repeated layout of physical points of the same face element as described in Example 1 of the present invention. In addition, the physical point acquisition equipment is also equipped with a measurement host and electronic maps, mobile communications and other technologies.

[0059] The geophysical surveying software 110 can receive the alarm information of the same surface element from the intelligent seismic team data center 140 in real time, and promptly remind the surveying team members to pay attention to the physical points of the same surface element through technical means including controlling equipment vibration, warning sound, prompt messages, etc.

[0060] (2) The method of avoiding repeated setting out of physical points of the same face element is applied to markerless construction

[0061] ① In this embodiment, a method for avoiding repeated staking of physical points of the same bin is applied to the arrangement of markerless layout and markerless drilling, specifically:

[0062] Before array deployment or drilling construction, the array team or drilling team uses a portable high-precision GNSS device to optimize, store, encrypt, and upload field physical points to an intelligent seismic team data center 140 based on a local server or cloud server. The portable high-precision GNSS device has built-in markerless construction software 120. The markerless construction software 120 includes the method for avoiding repeated staking of physical points in the same bin as described in Example 1 of the present invention. The development method and technology of the software are consistent with the development method and technology of the geophysical exploration-specific measurement software 110 including the method for avoiding repeated staking of physical points in the same bin as described in Example 1 of the present invention.

[0063] Similarly, the markerless construction software 120 can also receive real-time alarm information about the same surface element from the intelligent seismic team data center 140. If there are physical points in the same surface element, the team or drilling team construction personnel can be promptly arranged to pay attention to the physical points of the same surface element through technical prompts including control equipment vibration, warning sound, prompt messages, etc.

[0064] ② In this embodiment, a method for avoiding repeated staking of physical points of the same bin is applied to the markerless acquisition of earthquake sources, specifically:

[0065] In this embodiment, before the source acquisition team collects the excitation, they use a high-precision source navigation device to encrypt, upload, and save the detailed information of the pre-excitation physical points to an intelligent seismic team data center based on a local server or a cloud server. The high-precision source navigation device has a built-in source markerless construction system 130. The source markerless construction system 130 includes the method for avoiding repeated staking out of the same-surface element physical points described in Example 1 of the present invention. The development method and technology of the system are consistent with the development method and technology of the geophysical exploration-specific measurement software 110 including the method for avoiding repeated staking out of the same-surface element physical points described in Example 1 of the present invention.

[0066] After processing and calculation by the intelligent seismic team data center, if the same-surface element physical point is found, the earthquake source unmarked construction system 130 will immediately receive an alarm prompt. At the same time, it will also receive the recommended points calculated by the intelligent seismic team data center based on the completion status of the current pre-designed points nearby, reducing the difficulty of point selection.

[0067] In this embodiment, according to the difference between the local server or cloud server to which the intelligent earthquake team data center 140 belongs, 110 and 140, 120 and 140, 130 and 140 are connected through one or more of the self-organized local area network, 3G / 4G / 5G public network, etc., for encrypted uploading of physical point data, transmission of alarm information, etc.

[0068] In this embodiment, the intelligent seismic team data center 140 is based on either a local server or a cloud server, depending on specific production conditions. Using the aforementioned communication technology, the intelligent seismic team data center 140 obtains encrypted physical point information uploaded by physical point acquisition modules, such as software 110, software 120, or software 130, that incorporate the method described herein. After decryption and calculation, qualified points are stored. If physical points are found to be located within the same bin, a specific alarm message is sent to the acquisition module where the data resides, alerting the process to duplicate physical point placement within the same bin. The intelligent seismic team data center 140 can collect production data from the aforementioned data acquisition modules and, based on this information, provide feedback on the presence of identical bins, recommending point locations and guiding production processes.

[0069] The above description is merely an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
